Abstract
Description
- The present invention relates to a sunshade device for motor vehicles, comprising a sunshade that can be displaced between an inoperative position and an operative position with respect to a supporting structure, and a shape-memory actuator for controlling displacement of the sunshade from its inoperative position to its operative position.
- A device of the type referred to above is described and illustrated in the
document No. JP-A-62 006824 motor vehicle 1, equipped with awindscreen 2 and aroof 3 with awindow 4 delimited at the front by across member 5. In the case of application of the device according to the known art, thecross member 5 has, as clearly illustrated in Figure 1, a dimension in the longitudinal direction A of the motor vehicle that is relatively large, in so far as each of thesunshades 6 must be received, in its own inoperative condition, within saidcross member 5. Consequently, thefront edge 7 of thewindow 4 made in theroof 3 is sensibly retracted, a fact which, as has been said, does not enable the driver of the motor vehicle and the passenger sitting in the front seat to enjoy fully the advantages of the window on the roof. - The main purpose of the present invention is to overcome the aforesaid drawback.
- A further purpose is to provide a sunshade device with shape-memory actuation that is simple, has small overall dimensions, and is efficient and quiet during operation.
- With a view to achieving said purpose, the subject of the invention is a sunshade device having the characteristics referred to at the start of the present description and further characterized in that the aforesaid sunshade is constituted by the blind of a roller-blind device, comprising a supporting structure and a shaft on which the blind is rolled up, which is mounted on the supporting structure so that it can rotate, said shape-memory actuator comprising at least one shape-memory element that can be activated for controlling movement of the roller blind from the rolled-up condition to the distended condition.
- Thanks to the characteristic indicated above, in the condition where it is installed on the motor vehicle, the device according to the invention has small overall dimensions in the longitudinal direction of the motor vehicle, which enables sensible reduction in the transverse dimension of the front cross member of the roof panel with consequent advantages in the case where the vehicle is equipped with a sun roof with window. Of course, the invention can in any case be applied with practical advantage also on motor vehicles not provided with sunroof with a window.
- The shape-memory actuator can be of the type in which a shape-memory actuator element controls the movement of the sunshade only from its inoperative position to its operative position, engagement means being provided for withholding the sunshade in its operative position once this has been reached so as to enable de-activation of the shape-memory element. In the case of said solution, there are provided means for de-activating the engagement means and elastic means that bring back the sunshade into its inoperative position.
- In a second solution, a first shape-memory actuator element and a second shape-memory actuator element are provided for controlling movement of the sunshade into the operative position or into the inoperative position, respectively.
- In a third solution, the shape-memory actuator is of a bistable type, i.e., of the type in which each successive activation of the shape-memory actuator brings about movement of the sunshade from the inoperative position into the operative position or vice versa, the sunshade remaining each time in the position reached after de-activation of the actuator.
- The shape-memory element is preferably of the type that can be activated by electrical-supply means, which cause passage of an electric current through the shape-memory element, so as to heat it by the Joule effect beyond its transition temperature.
- According to a further characteristic of the invention, the roller blind constituting the sunshade has two longitudinal edges provided with a stiffening element in such a way that, in the distended condition, the sunshade has a substantially rigid and self-bearing configuration and projects in cantilever fashion from the roller-blind casing.
- The supporting structure of the roller blind is in turn connected to a fixing bracket by means of an articulated joint, which enables orientation of the sunshade in any desired position, for example in such a way as to lay it out parallel to the windscreen or parallel to a side window of the motor vehicle or in order adjust the angle of inclination of the blind in its distended configuration.
- In an example of embodiment, the shape-memory actuator comprises an elongated shape-memory element wound within a casing and made in such a way as to control rotation of the shaft for rolling-up of the blind via a gear transmission. The wound shape-memory device can be, for example, of the type forming the subject of the copending
European patent application No. 06425135.8 - In a variant, the shape-memory actuator can comprise one or more shape-memory wires arranged so as to bring about rotation of respective pulleys connected in rotation to arms for supporting the end edge of the blind, which can oscillate between a retracted position and an extracted position in which they cause unrolling of the blind from the roller device.
- Further characteristics and advantages of the invention will emerge from the ensuing description with reference to the annexed plate of drawings, which are provided purely by way of non-limiting example and in which:
- Figure 1 is a partial perspective view of a motor vehicle equipped with a sunshade shape-memory-actuator device according to the known art;
- Figure 2 is a view corresponding to that of Figure 1, which shows a motor vehicle provided with a device according to the invention;
- Figure 3 is a schematic perspective view of the device according to the invention, in the inoperative condition;
- Figure 4 is a perspective view of the device of Figure 2, in the operative condition;
- Figures 5, 6 and 7, 8 illustrate the aforesaid inoperative and operative conditions of the device of Figures 3 and 4 in a front view and in a side view, respectively;
- Figures 9 and 10 are perspective views of a second embodiment of the device according to the invention in the inoperative condition and in the operative condition, respectively; and
- Figures 11, 12 and 13, 14 show the aforesaid two operative conditions of the device of Figures 9 and 10 in a front view and in a side view, respectively.
- As has already been described above, Figure 1 shows the application of a sunshade shape-memory-actuator device according to the known art, for example of the type illustrated in the
document No. JP-A-62 006 824 front edge 7 of thewindow 4 of the roof. - Figure 2 illustrates a similar application of a device provided in accordance with the teachings of the present invention. In this case, the
front cross member 5 of theroof panel 3 of the motor vehicle has a very small dimension in the longitudinal direction A, which entails a very advanced positioning of thefront edge 7 of thewindow 4 made in theroof 3. In this way, also the driver and the passenger sitting in the front seat can enjoy fully the advantages of thewindow 4. - As may already be seen schematically from Figure 2, the motor vehicle is equipped with one or
more sunshade devices 8. In the case in point, two devices are provided, designed to be used respectively by the driver and by the passenger occupying the front seat adjacent to the driver. There is nothing, however, to rule out similar devices possibly being provided, for example, in areas corresponding to the rear side windows so as to be used by the passengers occupying the rear seats of the motor vehicle. - Each
device 8 is substantially constituted by a roller blind supported in an orientable way by a bracket fixed to the structure of the motor vehicle. - With reference to the embodiment illustrated in Figures 3-8, the sunshade proper, designated by the
reference number 6, is constituted by the roller blind of a roller-blind device. The blind 6 can be made of fabric or of a synthetic material and incorporates along its longitudinal edges two flexible-metal strips 6a, which wind within the casing of the device in the rolled-up condition of the blind, but have in any case a stiffness sufficient to maintain the blind 6 substantially in tension and rigid, i.e., self-bearing, in its distended condition in cantilever fashion outside the roller-blind casing. - As may be seen in particular from Figures 5 and 6, the blind 6 rolls up on two
end rollers 9 carried by awinding shaft 10, which is supported, in such a way that it can rotate, within acylindrical casing 11 having aslit 12 from which the blind 6 comes out. Rotation of thewinding shaft 10 is driven by a shape-memory actuator 13 of which the drawings show the outer casing. The shape-memory actuator 13 is of the type designed to set in rotation adisk 14 by means of a elongated shape-memory element, for example, in the form of a wire or strip, wound in a spiral or else in a helix. An actuator device of this type forms the subject of the copendingEuropean patent application No. 06425135.8 device 8, which causes the elongated shape-memory element to be traversed by electric current. Following upon passage of current, the elongated shape-memory element undergoes heating by the Joule effect above its transition temperature, so that the element tends to shorten, thus setting the disk-like body on which it is wound in rotation. Rotation of thedisk 14 gives rise to a corresponding rotation of atoothed sector 15, which is rigidly connected to thedisk 14 and rotates therewith around the respective axis ofrotation 16. Thetoothed sector 15 in turn meshes with a sprocket wheel 17 (Figures 7 and 8) carried by one end of thewinding shaft 10. - Thanks to the arrangement described above, activation of the shape-memory element causes rotation of the shaft for rolling-up of the blind from the condition corresponding to the inoperative position of the blind (Figures 3 and 5, 7) to the operative position (Figures 5 and 6, 8).
- As already mentioned above, activation of the shape-
memory actuator device 13 can be controlled by the user by operating a pushbutton, designated as a whole by 18 in Figure 3, which transmits a signal to anelectronic control unit 19, which provides electrical supply to the shape-memory actuator device 13. - In one embodiment, the device can be envisaged so as to maintain the blind 6 in the distended condition as long as the electrical supply of the shape-memory actuator is maintained. As said supply ceases, which can be obtained once again by actuating the
control pushbutton 18, the shape-memory element cools down and returns into its original condition, and retraction of the blind 6 in the rolled-up condition is obtained by means of elastic-return means, for example in the form of a spiral spring associated to thedisk 14 itself of the shape-memory actuator or to thewinding roller 10. - However, according to the invention, it is considered advantageous to ensure that the blind 6 will remain in its operative extracted position without requiring maintenance of the electrical supply of the shape-memory actuator. The simplest way to obtain this result is to use a shape-memory actuator of a bistable type. An actuator of this type has, for example, formed the subject of the European patent No.
EP-B-1 241 351 filed in the name of the present applicant. Basically, bistable operation is obtained by associating to the member driven by the shape-memory element either elastic means that tend to bring back the driven member into a resting position or a device for clamping the driven member in the operative condition into which it is brought when the shape-memory element is activated, the arrangement being such that, once the driven member has been clamped in its operative condition, a subsequent temporary activation of the shape-memory element causes de-activation of the aforesaid clamping device. In this way, the driven member is normally kept in its resting position by the aforesaid elastic means. Starting from this condition, if the shape-memory element is activated, the driven member is displaced into its operative condition, against the action of the aforesaid elastic means, until it causes engagement of the clamping device, after which the driven member remains in its operative condition even if the shape-memory element is de-activated. A subsequent activation of the shape-memory element causes de-activation of the clamping device and consequent return of the driven member into its resting position as a result of the elastic return means. - As an alternative to said solution, a first shape-memory element may be provided for causing displacement of the driven member from its resting position to its operative position, where it is clamped by an engagement device so as to enable de-activation of the first shape-memory element, as well as a second shape-memory element, which is designed to cause de-activation of the engagement device so as to bring about return of the driven member into its resting position under the action of elastic return means.
- To return to the embodiment illustrated in Figures 3-8, the entire structure constituted by the
casing 11 and thecasing 13 connected at one end of thecasing 11 is connected, by means of a ball-and-socket joint 20 located at the centre of thecasing 13, to an L-shaped supportingpin 21, projecting from abracket 22 provided withholes 23 for screws for fixing thebracket 22 to the structure of the motor vehicle. Moreover associated to thecasing 13 is agripping handle 13a, which enables manual orientation of the entire structure of the device exploiting the freedom of movement afforded by the ball-and-socket joint 20. In this way, the user can easily position thedevice 8 in the most convenient way, for example in a position corresponding to the windscreen of the motor vehicle or of a side window. In addition, the ball-and-socket joint 20 affords also the possibility of adjusting the angular position of theslit 12 from which the blind 6 comes out so as to vary, in the distended condition of the blind, the angle of inclination of the blind itself. - A further advantage of the device according to the invention is that it is always and in any condition manually controllable. For example, in the case of the embodiment described above with reference to Figures 3-8, at any moment the user can grip the end edge of the blind 6, when this is extracted in the condition of Figure 4, and push it so as to cause it to enter within the casing. Otherwise, the blind can also be unrolled manually outside the casing. Figures 9-14 refer to a second embodiment. In said figures, the parts that are common to the ones of Figures 3-8 are designated by the same reference numbers. The main difference with respect to the embodiment described previously lies in the way the shape-memory actuator means are made. This embodiment does not envisage an actuator with wound shape-memory element, but rather two shape-memory wires 24 (see Figures 11 and 12) are provided, which run within the
casing 11. Eachwire 24 has one end 24a fixed to thecasing 11, and the opposite end engaged around apulley 25 mounted so that it can rotate about an axis 26 on the structure of the casing 11 (see also Figures 13 and 14). Eachpulley 25 supports in rotation a flattenedmetal arm 27 having one end connected in rotation with therespective pulley 25 and the opposite end articulated in 28 on a slider 28a which is able to slide along a cross member 29 (see Figure 10) fixed to the free edge of the blind 6. Activation of the two shape-memory wires 24 causes rotation of the twopulleys 25 and consequent oscillation of the twoarms 27 from the retracted and mutually aligned condition illustrated in Figures 9 and 11 into the condition where they are rotated through 90° of Figures 10 and 12. - Associated to the
pulleys 25 are, for example, spiral springs, tending to bring back thearms 27 into the retracted condition illustrated in Figure 9. In a way similar to what has been described above with reference to the first embodiment, once the shape-memory element is activated, it can be kept in said condition by maintaining the electrical supply of the shape-memory element. Upon ceasing of the electrical supply, the springs associated to thepulleys 25 bring back the blind into the retracted condition. Once again in a way similar to what has been described with reference to the first embodiment, it is, however, possible to provide a device for engaging the blind in the distended condition, which enables the blind itself to be kept in said condition even after de-activation of the shape-memory element. In this case, it is necessary to provide means for de-activation of the engagement device in order to bring the blind back into the retracted condition. Said result can be obtained, for example, by providing a further shape-memory element (not illustrated), which is activated by the user when he presses thepushbutton 18 for governing rolling of the blind 6. - Of course, without prejudice to the principle of the invention, the details of construction and the embodiments may vary widely with respect to what is described and illustrated herein purely by way of example, without thereby departing from the scope of the present invention.
